Malcolm Thomas is headed to Miami to workout for the Heat on Tuesday and Wednesday, a league source told RealGM Monday.

Thomas remains a free agent and is searching for a guaranteed contract.

In their search for an athletic big man to round out the roster, the Heat have become intrigued enough with the 6-foot-9 Thomas to bring him in to train in front of management and the coaching staff.

In addition to his workouts with Miami, Thomas is weighing a couple NBA options and potential high-level EuroLeague situations, sources said. His two-day workout for the New York Knicks a couple weeks ago went well, but the Knicks are undecided as to how they want to fill out their roster.
